P3 b是人类事件相关EEG电位的重要组成部分。P3 b与意识、记忆编码和策略图式更新等有关,但也有证据表明它与决定如何对所呈现的刺激做出反应密切相关。P3 b在很少发生的刺激下较大,在频繁发生的刺激下较小。在这里,我们调查的程度,这种古怪的效果取决于选择和执行的反应。参与者按下两个键中的一个来回应两个字母中的一个,其中一个很少出现,另一个经常出现。关于字母键映射的信息由第二刺激提供。在不同的区块中,这种映射刺激要么是恒定的,要么是随机变化的,要么是在字母之前或之后。当反应延迟时(通过等待字母后面的恒定映射刺激),奇球效应会降低,当反应无法分配给字母时(因为字母后面是不同的映射刺激),奇球效应会进一步降低。这一证据表明,P3 b与决策过程密切相关,可能反映了刺激-反应联系的重新激活。
P3b is a prominent component of human event‐related EEG potentials. P3b has been related to consciousness, encoding into memory, and updating of strategic schemata, among others, yet evidence has also been provided for its close relationship with deciding how to respond to the presented stimuli. P3b is large with rarely occurring stimuli and small with frequent ones. Here, we investigate the extent to which this oddball effect depends on selecting and executing responses. Participants pressed one of two keys in response to one of two letters, one of which was presented rarely and one frequently. Information about letter‐key mapping was provided by a second stimulus. In different blocks, this mapping stimulus was either constant across trials or varied randomly, and either preceded or followed the letter. The oddball effect was reduced when responses were delayed (by waiting for the constant mapping stimulus following the letter) and was further reduced when responses could not be assigned to the letters (because letters were followed by varying mapping stimuli). This evidence suggests that P3b is closely related to decision processes, possibly reflecting reactivation of stimulus‐response links.
